Abstract (en)
[origin: WO03102440A1] The device for detecting the amount of splash water to which a brake pad is subjected on a wet roadway is comprised of a test brake pad, whose fiction lining is hygroscopically designed so that it can absorb at least 5 %, preferably at least 10 % water. Surprisingly, it has been shown that no complicated test structures are necessary for determining the amount of splash water. In a test phase, vehicles can be easily tested by replacing their stock brake pads with test brake pads. By virtue of the fact that the inventive friction lining is hygroscopic, a direct correlation exists between the water absorption of the friction lining and the amount of moisture led to the friction lining in the form of splash water and air humidity. This enables the amount of splash water, to which a brake pad is subjected on a wet roadway, to be determined with high precision and without a large amount of technical complexity. This is of vital importance to road safety since splash water, in principle, has a negative effect on the coefficients of friction of a brake pad.
